This study presents the data concerning the intensity of lipid peroxidation in seedlings of Arabidopsis thaliana, which were grown under the prolonged water stress on the agarized sterile medium. Growth parameters, such as length of the main root and fresh matter were measured. The seedlings of A. thaliana subjected to water deficit exhibited a decrease in the growth of the main root and fresh weight in comparison to the control plants. Since peroxidation processes due to the concentration of malonic dialdehyde and the level of chemiluminescence of plant homogenate decreased at the end of the experiment, it was concluded that plants were able to adapt to water stress conditions.

W pracy badano natężenie peroksydacji lipidów w siewkach Arabidopsis thaliana w warunkach długotrwałego stresu wodnego. Mierzono takie parametry wzrostu roślin jak długość głównego korzenia i świeżą masę roślin. U siewek Arabidopsis thaliana w warunkach stresu wodnego zaobserwowano zahamowanie wzrostu korzeni i spadek świeżej masy siewek. Ponadto zanotowano obniżenie poziomu aldehydu malonowego, jak również intensywności che- miluminescencji pod koniec eksperymentu, co wskazuje na zmniejszenie natężenia peroksydacji lipidów i możliwość adaptacji roślin do warunków stresu wodnego.
